On 2 different flights the wifi was horrible and there was no drink or snack service.

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

It wasn't really their fault it was the horrible winds and we just got unlucky.

There was no FREE wi-fi nor entertainment screens at all.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

There is no free Wi-Fi or screens in the seats for this flight. It would be nice if they had actual actual healthy drink options like a flavored sparkling water. The flight was very dark because nobody was sitting on the left side and they didn't open any of the windows. The plane was kind of and had small overhead bins. There was no distinguishable difference between economy and comfort Plus.

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

I recently had foot surgery and traveled my first time needing assistance. The flight attendants on this flight went above and beyond accommodating my partner and I. I had a panic attack from the medication I was on, and the flight attendants made me feel safe and comfortable when they saw me in distress. They relocated me to an area of the aircraft that made me feel more comfortable and we had our own row which helped reduce my anxiety tremendously.

On time departure and early arrival. Excellent customer service from flight crew

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

Everything was really good but the seats are not very comfortable.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

The boarding attendant was slightly rude when I asked about checking our stroller. Made me feel like I was bothering her.

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

Not much seat room, but that was unexpected. But the seat headrest was very uncomfortable.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it
